For cars is way more feasible just having two electrical-charged metal bars that always touch the underside of your car when is in the garage, and if they are far apart it's complete safe (i.e: children can't touch both at the same time)

Children may have pieces of metal such as bicycles, or they may walk across such bars while holding hands. I bet there are way more failure modes with such an approach (kids never drop buckets of water inside garages, for example) I would put in a few more safety methods.

  You can also have a 4 heavy switches under the 4 wheels, that way a very heavy object (the car) must be there over all of them to turn on the electricity.

    And then you spill some water while the car is parked in the garage and bam, 440V right across the heart.

      Are you serious? To touch the car the metal bars must be above the floor, unless you spill tons of water enough to fill the garage you should be okay.
